A high-performance mobile suit used by the Oldsmobile Army during the early UC 0120s, the OMS-14RF RF Gelgoog ("RF" being short for "ReFined") bears a strong resemblance to the MS-14A Gelgoog used by the old Principality of Zeon during the One Year War in UC 0079. Despite its looks, the RF Gelgoog is up to par in terms of modern performance standards, even exceeding the mass produced contemporary OMS-06RF RF Zaku used by most Oldsmobile troops. However, the RF Gelgoog is a very costly unit, and it's only produced in limited numbers, with these units relegated to use by high-ranking officers or ace pilots.
